[QUOTE="Brian jojade, post: 24880, member: 211"] Re: using "wye or Y" cables and associated questions When you throw phantom power into the mix, using simple resistor summing circuits isn't going to do you well. The phantom power will also have to run through the resistor, thus reducing the phantom voltage. A typical microphone will have an impedance of 200 ohms. The circuits drawn would series 950 ohms with that 200 ohms, thus dropping the voltage significantly. If you started with 48 volts, you would effectively end up with around 10 volts to the mic. While some mics will work with voltages that low, others most certainly will give you grief. Definitely not a good idea to use this with a phantom powered system. [/QUOTE]
